量子真空对宇宙学常数的贡献为零：真空能量不受引力的证明
The contribution of the quantum vacuum to the cosmological constant is zero: proof that vacuum energy does not gravitate
摘要：
许多理论物理学家的共识是，计算出的量子真空对宇宙总能量密度的贡献大约是观测到的能量密度的$10^{121}$倍。这被认为是有史以来最糟糕的理论预测之一。然而，如图所示，这种巨大的真空能量本身并不能对正常物质施加力。因此，量子场论预言的巨大真空能量密度对宇宙的普通能量密度没有贡献，不是引力场的来源，因此，对宇宙学常数的值没有贡献。
英文摘要：
The consensus among many theoretical physicists is that the calculated contribution of the quantum vacuum to the total energy density of the universe is approximately $10^{121}$ times the observed energy density. This is thought to be one of the worst theoretical predictions of all time. However, as shown here, this immense vacuum energy cannot in and of itself exert forces on normal matter. As a result the huge vacuum energy density predicted by quantum field theory does not contribute to the ordinary energy density of the universe, is not a source for gravitational fields, and, as a result, does not contribute to the value of the cosmological constant.
